Interior design couple Nate Berkus and Jeremiah Brent listed their pristine Greenwich Village penthouse in November of last year for $10.5 million. Though they undertook a beautiful update (which was featured as the cover story in last September’s issue of Architectural Digest), this was a steep increase, so it’s not a total surprise that the selling price came in slightly lower at $9.8 million. According to the Observer, the buyer is “financier-slash-jewelry designer” Charles de Viel Castel.

The duplex spread was renovated to hold entertaining on one level with the family quarters (three bedrooms) below. There’s 10.5-foot coffered ceilings, four fireplaces, a wrought iron staircase, and a glass-enclosed office.

A modern kitchen opens to a formal dining room; between them, pocket doors can be opened or closed depending on the setting. The kitchen, which has a gorgeous wall of windows and skylights, is described as a “space only found in old-world New York mansions.”

The very large master suite boasts a “dressing room larger than most bedrooms,” according to the listing. The marble master bath is not too shabby, either.

Berkus and Brent had previously gushed over the pre-war co-op at the Emery Roth-designed 39 Fifth Avenue: “We couldn’t stop thinking about the apartment, believing we were meant to live there…we were able to create the home of our dreams.” Their daughter Poppy was born last March, which could be the reason for the move.
